Light bleeding? Need advise pls .

Hi everyone I am 11 days late after AF was due and today I am experiencing brownish colour bleeding when I wipe. I initially thought my period started but than the bleeding is not getting heavy like my period but actually it is almost gone . I am supposed to start my first round of clomid tomorrow so what should I do now? I know it's too late for an IB . Should I take the clomid ? I can't see the doctor until 2 days so what should I do? Anyone ever experienced this much late IB?
